Marriage Problem Analysis

I chatted with my mom several times this month. There are always two major topics in our conversation. First, she is concerned about my sister who has not married yet. Second, she wants me to marry an Iranian girl from her friends or someone who she knows.

I thought about it, I can't marry someone in my home country because of several reasons:

1- My visa in single entry. It is a big risk if I want to go back to Iran now. I may not get visa again.
2- I need to know someone before marriage. Even though I took the risk and go back there, I can't stay more than 3 months. How can I know someone and marry her in this short amount of time?
3- Let's suppose that I could marry someone where. What if she couldn't get visa then?
4- If I get my degree, I can't go back to my home country because I need to server two years in military. In fact, I loose all my advantages of getting a degree here.
5- Even If I marry one of them, I can't go back to my home country because of military services, and she will need to visit her family in Iran, and I can't go with her. It may cause lots of problems in the future.

I have two options only; either find someone here, or go back to my home country forever. I don't want to go back there without getting a GC here because I loose many things. A degree is not enough for the things I am going to do. In addition, I am here, and I am 30 now, and it takes at least three years to finish my degree. So, I have three years to decide about staying here or not. Therefore, I just need to focus on the first option, finding someone here.

If I want to marry someone here, I have three choices. First, I can choose an American girl because there are so many of them living here. Second, I can find an Iranian second generation. They are the best because they are both Iranian and American. Third, I can marry an Iranian student who has the similar situation like me.

Since there are so many American girl here, I need to know whether I can live with them or not. I can't start with Taylor definitely, but I can meet any other girl. Second generation Iranian are rare to find. If I could find, I seriously consider her. Iranian students are good, but there are not many choices again, and it should be hard to find a match. So, the first thing is to know about American girls.
